KINETOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 590,7 6 6, datedSeptember 28, 189'?. Application filed February 16, 1897. Serial No.623,753. (No model.)

To all whom, it' may con/cern:

Beit known that I, FRANQOIS MORAND, a citizen of the French Republic,and a resident of Aix-les-Bains, France, have invented certain new anduseful Improvements in Apparatus for Obtaining and ExhibitingChronophotographs, of which the following is a specication.

The construction of this apparatus is shown in the annexed drawings.

Figure l is a vertical sectional View of the apparatus. Fig. 2 is atransverse sectional View. Fig. 3 is a horizontal cross-sectional view.Figs. 4 and 5 are detail views of parts.

The apparatus as arranged for taking the photographs is composed of abox A, in which the mechanism is arranged.

E is the box containing the sensitive pellicle or film.

F is a box in which the exposed pellicle is rolled up in proportion toits movement.

II is a plate carrying the principal parts of the mechanism.

I I are rollers for guiding the pellicle along the plate.

The pellicle K, starting from the roller M, is partly rolled at eachaction of the mechanism upon 'the roller N and passes before the windowGr in the plate.

The mechanism is composed of a wheel P, operating by means of a pinion Qa shaft R, which carries the screen S. At the extremity of this shaft isfixed a plate T, which carries a crank-pin O, the total displacement ofwhich corresponds to the height of the picture to be produced. Thescreen S may be a transparent disk of mica or any other material and iscut away forabout a quarter of its circumference. It is formed of orcarries three colored sectors, of which the sum with equal quantity andradiations gives White light on the rotation of this disk. The firstquadrant is red-orange. The second quadrant is greenyellow, and thethird quadrant is blue-violet. This disk allows in its rotation thechange of the pictures without the retina undergoing any absolutesuppression of the light in any one of the periodical actions of themovement. This avoids scintillation. The same disk can serve forobtaining negative photographs by varying the size of the cut. A

curved slot n is provided in a plate V, carrying two rods X and y,guided by supports s and 1f, fixed upon the plate. The curve is sotraced as to give at the start and the end of each course a stoppageallowing the engaging and the disengaging of the pins which produce thedisplacement c f the pellicle for an equal and regular quantity at eachturn of the crank-pin. Upon the plate V is an arm b, carrying twonipples CZ e, through which are holes which serve as guides for the pinsf g, connected by the rod h. The pins f g follow, therefore, themovement of the arm b. These pins are pushed outward for engaging thefilm by two springs t' t', and for the disengagement at the end of thecourse they are pushed back by the two springs jj.

Referring to Figs. 4 and 5, the two side plates or guides l Z., in whichthe arm b is guided, are provided also each with two parallel grooves lZ2, communicating with each other at their upper and lower ends. Inthese grooves l/ l2 are guidedthe ends of the rod 7L.

Each course of the apparatus is as follows: The plate V with its arm l)being at the top of its course, the rod h will lie with its extremitiesengaged in the grooves l/, provided on the sides of the lateral cheeksguiding the arm l). The rod 71., carrying the two pins, is therefore atthe top of its course and has been pushed by the two springs tz' so thatthe pins f g penetrate into the holes provided along the sides of thepellicle. lVhile this engagement is effected the crank-pin O is passingin the curve a the concentrical part in a, which provides a dead-point.As soon as the engagement is effected the carriage V sinks the wholelength of itscourse, and thus displaces the pellicle, while the screen Scovers the window. At the end of the course the springs jj push the rod7L with the pins f g back during the movement of pin O in the part p pof the slot, and the mechanism rises again while the section of pellicleuncovered by the screen S is exposed or in view, and'so on. A smallspring r is caused to press on the pellicle by means of the cam-facewhich the back of the plate T forms while the picture is stationary.

Having now particularly described and ascertained the nature of thisinvention and in what manner the same is to be performed, I declare thatwhat I claim is IOO l. In means for taking and exhibitingchronophotographs, the combination with means for guiding a pellicle ofguides leach having connected grooves Z/ Z72 with a rod 7L having itsends engaging in the grooves of the guides I, springs i' i" and j j fortransferring the rod from each groove to the other, pins on said rod 7Lfor engaging the pellicle while said rod 7i is in the grooves which arenearer the pellicle and means for reciprocating the rod in direction ofthe movement oi' the pellicle for the purpose set forth.

2. The combination ot' a rotary shaft, a crank-pin O, a plate V withslot u for engagement of said pin, means for rectilinear guiding of saidplate, an arm l) on said plate, perforated nipples d e, pins fg loose insaid nipples, a rod 7L carrying said pins and means for approaching saidrod 7L to the arm prior to movement of the latter in one direction7 andnf'ithdrawing it therefrom prior to movement thereof in the reversedirection for the purpose set forth.

3. The combination with a Window and means for causing a pellicle topass across said Window, of a screen adapted to revolve in a centerlaterally of the window the said screen having,` a sector-shaped recessand hai ing the remainder composed of transparent colored sectors, thesum of the colors of which With equal quantity and radiation areequivalent to White light.

In Witness whereof I have signed this spcci fication in presence of twowitnesses.
